Patent number: 7492980Abstract: In accordance with one exemplary embodiment the invention provides a multi-parameter fiber optic sensing system with an aperiodic sapphire fiber grating as sensing element for simultaneous temperature, strain, NOx, CO, O2 and H2 gas detection. The exemplary sensing system includes an aperiodic fiber grating with an alternative refractive index modulation for such multi-function sensing and determination. Fabrication of such quasiperiodic grating structures can be made with point-by-point UV laser inscribing, diamond saw micromachining, and phase mask-based coating and chemical etching methods. In the exemplary embodiment, simultaneous detections on multi-parameter can be distributed, but not limited, in gas/steam turbine exhaust, in combustion and compressor, and in coal fired boilers etc.Type: GrantFiled: April 22, 2008Date of Patent: February 17, 2009Assignee: General Electric CompanyInventors: Kevin Thomas McCarthy, Kung-Li Justin Deng, Hua Xia, Michael Joseph Krok, Avinash Vinayak Taware

Patent number: 7469077Abstract: A sensing module positioned about an optical fiber cable having a long axis. The optical fiber includes a core that transmits light through the optical fiber cable. The sensing module includes a first short-period fiber grating positioned about the core. A second short-period fiber grating is positioned about the core and at a distance along the long axis with respect to the first short-period fiber grating. At least one of a long-aperiod fiber grating and a long-period fiber grating is positioned between the first short-period fiber grating and the second short-period fiber grating. A fiber cladding is positioned around the long-period grating and/or the long-aperiod grating of the sensing module. A sensing skin is positioned about the fiber cladding and includes a chemical gas active material.Type: GrantFiled: May 14, 2008Date of Patent: December 23, 2008Assignee: General Electric CompanyInventors: Hua Xia, Kung-Li Justin Deng, Kevin Thomas McCarthy, Avinash Vinayak Taware
